Common Air Conditioning Problems

Improper operation is one of the most common air conditioning problems known today in the air conditioning industry. Make sure you close all your home’s windows and outside doors whenever your air conditioner is on. For all room air conditioners, isolate the room or a group of connected rooms as much as possible from the rest of your home.

Most common air conditioning problems result from wrong installation, poor service procedures, as well as inadequate maintenance. Wrong installation of a central air conditioner can lead to leaky ducts and low airflow. Mostly, the amount of refrigerant in the system known as the refrigerant charge fails to match the specifications of the manufacturers. If the right refrigerant charging is not done during installation, the performance and the efficiency of the air conditioning unit can be impaired. Unqualified technicians often fail to discover refrigerant charging problems or even make existing problems worse by adding more refrigerant to an already full system. Make sure you know the right questions to ask your technician whenever you have to hire one to ensure you get the best services.

Most air conditioner manufacturers produce very rugged, high quality products. Once your air conditioner fails, the first thing you should do would be to check the fuses and circuit breakers. Make sure you allow the unit to cool down for at least 5 minutes. If your central air conditioning unit stops working on a hot day, it is possible that the high pressure limit may have been tripped; you can reset it by pushing the button, located at the access panel of the compressor.

REFRIGERANT LEAKS

Once you notice your air conditioner is low on refrigerant, it means it was either undercharged during installation or leaks. If it leaks, adding more refrigerant is not the solution to the problem. You need to hire a trained heating and air conditioning technician to help you discover and fix the leak, test the repair for efficiency, and then charge the system with the right amount of refrigerant. Never forget that the efficiency and performance of your air conditioner is greatest when the refrigerant charge exactly matches the manufacturer’s specification, and is neither overcharged nor undercharged. Refrigerant leaks can equally be quite harmful to the environment.

INADEQUATE MAINTENANCE

Once you fail to prevent the filters and air conditioning coils from becoming dirty, the air conditioner cannot be able to work properly. and this can lead to failure of the compressor or fans.

ELECTRIC CONTROL AND FAILURE

The compressor and fan control can easily wear out, especially when the air conditioner turns on and off frequently, especially when the system is oversized. Electric connections and contacts should also be checked during a professional heating and air conditioning maintenance because corrosion of wires and terminals is also a problem in several systems.

SENSOR PROBLEMS

All room air conditioners feature a thermostat sensor, located behind the control panel, which measures the temperature of the air coming into the evaporative coil. If the sensor gets knocked out of its normal position, the air conditioner could recycle constantly or behave erratically. The sensor ought to be near the coil but doesn’t need to touch it; adjust its position by carefully bending the wire that holds it in place.
